International 4700-4900 Diesel Fuel Tanks

Frequently Asked Questions About International 4700-4900 Diesel Fuel Tanks

Will this fuel tank fit my International 4700 or 4900 without modification?

Fuel tanks vary by capacity, mounting hole pattern, strap style, and frame rail spacing depending on the model year and chassis configuration. Before ordering, check the tank's listed capacity and mounting dimensions against your truck's original tank and confirm the strap or bracket style matches your frame setup. If you're unsure, comparing part numbers with your dealer or checking your VIN-specific specs is the safest way to avoid a mismatch.

What material are these fuel tanks made from, and does it affect performance?

Diesel fuel tanks for the 4700-4900 series are typically constructed from aluminum or steel. Aluminum tanks resist corrosion better and are lighter, which can help with fuel efficiency, while steel tanks tend to be more affordable and durable against physical impact. Either option should hold up well when properly installed and maintained, so your choice often comes down to weight, budget, and personal preference.

How do I know what size fuel tank I need?

Fuel tank capacity depends on your truck's application, route length, and existing fuel system setup. Measure your current tank or check your build sheet for the original capacity before selecting a replacement. Installing a tank with significantly different dimensions may require additional bracket or strap adjustments, so matching capacity and physical size to your original equipment is the most reliable approach.

Can I install a replacement fuel tank myself, or should I have a professional do it?

Installation involves draining and disconnecting the old tank, transferring or replacing straps and mounting hardware, and reconnecting fuel lines and sending units. While experienced diesel techs and shop owners often handle this themselves, it does require proper tools, safe fuel handling practices, and attention to line and sender compatibility. If you're not comfortable working around fuel systems, having a qualified technician complete the install is recommended.

Do these tanks come with mounting straps, sending units, or other hardware included?

This varies by listing, so it's important to check the product description carefully. Some tanks are sold bare and require you to reuse your existing straps, sending unit, and fuel lines, while others may include additional hardware. If a listing doesn't specify, reach out to our team before ordering to confirm exactly what's included so you're not caught short on install day.
